Question

The frequency band used in the downlink of satellite communication is

• A. $9.5to2.5GHz$
• B. $896to901MHz$
• C. $3.7to4.2GHz$
• D. $840to935MHz$
• E. $3.7to4.2MHz$

Answer 1

The correct option is C

$3.7to4.2GHz$

Explanation for the correct option:

1. Satellites provide signals to Earth-bound antennas using radio waves. The antennas then pick up these signals and analyze the data they carry.
2. The frequency at which an earth station receives a satellite signal is known as the downlink frequency of the satellite.
3. The downlink frequency range is $3.7to4.2GHz$.

Hence, option C is the correct option.
